Description

Description: TECHNICAL FIELD The present invention relates to a method and apparatus for measuring the weight of a walkable animal within a short time by determining the weight value of the walkable animal while walking. .

[Conventional technology]

In the case of measuring the weight of a walkable animal, conventionally, the entrance gate is first opened, and the walked animal is allowed to walk one by one on a weighing machine whose exit is closed. Then, the walking animal is made to stand still or close to it on the weighing machine, the weighing value data is measured in this stable state, and the obtained data is calculated to obtain the weight value. When accurate weighing data was obtained, the exit date was opened, and the walking animal was allowed to walk and lowered from the weighing machine (see, for example, JP-A-59-73735 and JP-A-60-30626).

However, according to such a measuring method, stable weight value data cannot be obtained until the walkable animal becomes substantially stationary on the weighing machine. Therefore, it took a great deal of time to weigh a large number of walking animals.

Therefore, a method and an apparatus for measuring the weight of a large number of animals in a short time have been filed by the same applicant as the present applicant (see Japanese Patent Application Nos. 63-108267 and 63-109589).

In other words, this is to allow the resting weight of one walkable animal to be obtained in a short time, for which purpose the walk to place the walkable animal on the scale is followed by weighing. The resting weight of the animal is read by weighing while walking on the scale while actively walking on the scale. When we obtain the weight value data while walking the animal on the weigher in this way, by actively walking on the weigher with a rhythm, the spirit of the animal that can walk is directed toward the walking itself. Therefore, since the mind and body of a walkable animal on the weighing machine show a stable state together, it is possible to place the animal on the weighing machine rather than when it is forcibly stopped substantially on the weighing machine and then weighed. It can be completed in a short time from the time when it is finished to be taken down.

[Problems to be Solved by the Invention]

However, the above weight measuring method and apparatus include
There are still the following points to be improved.

Since the weighing value data that is sequentially captured fluctuates, it is unavoidable that an accurate static weight value cannot be obtained without obtaining a sufficient amount of weighing value data, but the weight range that requires accurate measurement. Even for walking animals that are outside weights, in other words, for walking animals that do not need to be measured, once they are placed on the weighing platform, they must spend the same time as the walking animals that need to be measured. Workers had to spend wasted time. By the way, the weight range required to measure a walking animal is arbitrarily set according to various situations.

Also, if there are many walking animals that require measurement, place a large number of animals in front of the entrance gate,
It was difficult to quickly open the entrance gate and place it on the weighing platform.

Further, when the weighing is finished, it is troublesome to sort the walking animals having a static weight value which needs to be measured and the walking animals having a static weight value which is not so as to be guided by the worker.

The present invention has been made in view of the above circumstances, and an object thereof is to eliminate the above drawbacks.

[Regarding the Invention of Claim 1] [Means for Solving the Problems] The features of the weight measuring method for a walkable animal according to the present invention are as follows.

(1) While the animal is walking on a weighing machine, the weighing value data of the walking animal obtained by the weighing means is sequentially taken in, (2) the initial data section is set from the weighing value data, (3) The initial static weight value of the animal is read from the weighing value data in the initial data section, and (4) when the initial static weight value is within a set range, the weighing value data is larger than the initial data section. (5) The rest weight value of the animal is read from the weighing value data in the valid data section.

[Operation of the Invention of Claim 1] In the invention of claim 1, an initial setting section is set from the obtained weighing value data, and an initial static weight value is read from the weighing value data in this initial setting section. If this initial static weight value is outside the set range, the weighing is stopped and the next animal is weighed. On the other hand, if it is within the set range, an effective data section larger than the initial data section is set from the weighing value data, and the static weight value of the animal is accurately read from this effective data section.

[Advantageous Effects of the Invention of Claim 1] Due to the above action, an animal having an initial static weight value out of the set range can walk without being fully weighed. It is possible to quickly shift to the weighing of animals.

[Invention of Claim 2] [Means for Solving the Problems] The present invention obtains the walking periodicity from the weighing value data, and sets the initial data section and the effective data section based on the walking periodicity. There is a feature in doing it. The walking periodicity referred to here is a fluctuation cycle of the weighing value data due to a weighing fluctuation factor added to the weighing means for the animal to walk. This variation factor may be a temporal variation of the position of the center of gravity due to the walking of the animal or a temporal variation of the energy generated / dissipated in the muscles of the animal. Since this fluctuation cycle is associated with the walking of the animal, the fluctuation cycle of the weighing value data can be associated with the walking cycle of the animal. As described above, since the walking cycle is induced by riding on the rhythm caused by the walking of an animal that can walk, for example, the weighing value is averaged in units of one cycle period of the walking movement of the animal on the weighing machine. It is believed that this allows the static weight of the animal to be read on the balance.

[Operation of the Invention of Claim 2] The gait periodicity is obtained from the measured value data. Based on this walking periodicity, an initial data section for detecting the initial static weight value and an effective data section for reading the static weight value are set.

[Effect of the invention of claim 2] By setting the initial data section and the effective data section based on the walking periodicity, the weighing value data is small in spite of a small amount of weighing value data during a short time when the animal walks on the weighing machine. The resting weight of a walkable animal can be read relatively accurately.

[Inventions of Claims 3 and 6] [Means for Solving the Problem] In the invention of Claim 3, the method of determining the starting point when setting the initial data section from the weighing value data exceeds a threshold value. The feature is that it is the time of the maximum value.

The invention of claim 6 is characterized in that the method of determining the starting point when setting the valid data section from the weighing value data is a time point of a maximum value exceeding a threshold value.

(Operation of the invention of claims 3 and 6) When the animal walks on the weighing surface, when the leg comes into contact with the weighing surface, the weighing value makes a remarkable peak and the maximum value appears. The change in the weighing value is comparatively gentle except when it touches the weighing surface, and no remarkable peak-like maximum value appears. In the present invention, the place corresponding to the break of one cycle of the walking animal of the animal on the weighing surface, that is, the first time point of the maximum value exceeding the threshold value is captured as the starting point of the initial data section or the effective data section. .

[Effects of the Invention of Claims 3 and 6] With this, the starting points of the initial data section and the valid data section can be appropriately determined with reference to the maximum value exceeding the threshold value of the series of weighing value data.

[Invention of Claims 4 and 7] [Means for Solving the Problem] In the invention of Claim 4, a method of determining an end point when setting the initial data section from the weighing value data is a constant cycle from the start point. It is characterized by what is later.

The invention of claim 7 is characterized in that the method of determining the end point when setting the valid data section from the weighing value data is after a fixed period from the start point.

[Operation of the Invention of Claims 4 and 7] It is preferable that the maximum value is captured from the weighing value data group, and this is used as a periodic starting point in the initial data section or effective data. As described in. In the present invention, the next one walking cycle or the next plural walking cycles corresponding to the starting point is detected from the maximum value in the weighing value data group, and the initial data section and the end point of the effective data are determined based on the detected maximum value.

[Effect of the Invention of Claims 4 and 7] If the initial data section and the end point of the effective data are determined in this way, the weighing value data can be obtained for each walking cycle, and it is appropriate when averaging processing is performed. It is possible to determine the section. Therefore, the static weight of the walking animal can be read accurately and quickly even with a small amount of weight data.

[Invention of Claims 5 and 8] [Means for Solving the Problem] In the invention of Claim 5, a method of determining an end point when setting the initial data section from the weighing value data is a predetermined time from the start point. It is characterized by what is later.

The invention of claim 8 is characterized in that a method of determining an end point when setting the valid data section from the weighing value data is after a predetermined time has elapsed from the start point.

[Operation of the Invention of Claims 5 and 8] It is preferable to capture the maximum value from the weighing value data group and use it as a periodic starting point in the initial data section or effective data. As described in. In the present invention, the time point when a predetermined time has elapsed from the start point is set as the initial data section or the end point of valid data.

[Effects of the Invention of Claims 5 and 8] When the end points of the initial data section and the valid data are determined in this way, when the end points cannot be obtained by the method of the inventions of claims 4 and 7, that is, the animal is a weighing machine. Even if the vehicle stops at the top and the end point based on the walking cycle cannot be obtained, effective weighing value data can be obtained.

[Regarding the Invention of Claim 9] [Means for Solving the Problem] The features of the invention of Claim 9 are (1) the walking obtained by the weighing means while the animal is walking on a weighing machine. An input means for sequentially taking in the weighing value data of the animal therein, (2) means for setting an initial data section from the weighing value data, and (3) an initial static weight of the animal from the weighing value data in the initial data section. (4) means for calculating a value; (4) means for setting an effective section larger than the initial data section from the weighing value data when the initial static weight value is within a setting range; (5) in the effective data section The weight measuring device is configured to include a means for calculating the static weight value of the animal from the weighing value data.

[Operation of the Invention of Claim 9] In this weight measuring device, weighing value data is obtained by the weighing means from the animal walking on the weighing machine and sequentially fetched. An initial data section is set based on the taken weighing value data, and an initial static weight value of the animal is calculated from the weighing value data in this initial data section. When the initial static weight value is within the set range, a valid data section larger than the initial data section is set from the weighing value data, and the static weight value of the animal is calculated from the weighing value data in the valid data section. .

[Advantageous Effects of the Invention of Claim 9] As described above, the weight measuring device according to the present invention has
It is possible to automatically execute the above-mentioned operation of the invention.

[Invention of Claim 10] [Means for Solving the Problem] The feature of the invention of Claim 10 is that an entrance gate is provided on the entrance side of the weighing machine, and the next animal is provided behind the entrance gate. It is characterized in that a waiting area for waiting is provided and a separator for separating the waiting animal from other animals is provided behind the waiting area.

[Operation of the invention of claim 10] When weighing a plurality of ambulatory animals, when the weighing of one animal is finished, the next animal from the plurality of animal groups must be immediately placed on the weighing machine. It may take some time to lag because it fits.

When one animal to be measured passes through the entrance gate and gets on the weighing machine, the entrance gate is closed and the separator is opened. Then, after leading the next animal from the group of animals into the waiting area, the separator is closed and separated from the group of animals. When the weighing is finished, the entrance gate is opened and the waiting animal is placed on the weighing machine.

(Effect of the invention of claim 10) If the next animal is made to stand by in the waiting area in advance during the weighing of the previous animal as described above, the next animal group is selected after the weighing of the previous animal is completed. Eliminates the need to choose animals. In other words, since the next animal is selected by using the time when the previous animal is weighed, the above-mentioned wobbling is eliminated, and even if there are many walking animals, the weighing can be completed quickly.

[Regarding the invention of claim 10] [Means for solving the problem] The feature of the invention of claim 11 is that, on the outlet side of the weighing machine, the animal and the setting range in which the initial static weight value falls within the setting range. The point is that there is a sorting device that sorts animals from the outside.

[Advantageous Effects of the Invention of Claim 11] The sorting device automatically sorts an animal whose static weight value is within the set range and an animal whose static weight value is outside the set range. Incidentally, in determining whether or not the static weight value is within the set range, only the initial static weight value may be used, or the static weight value obtained based on the valid data section may be checked again. .

[Effect of the Invention of Claim 11] It is possible to sort an animal whose static weight value is within the set range and an animal whose static weight value is out of the set range without requiring a special worker.

The tag recognition means (4) is provided, and the reception information of the tag recognition means (4) is also input to the measurement processing section (H). That is, the measurement processing unit (H) identifies one of the plurality of cows and measures the weight of the walking cow along with the identification information.

As shown in FIG. 3, the measurement processing unit (H) has an input means (5) for receiving an electric signal indicating a weighing value sent from the weighing means (S), an initial static weight value and a static weight value. It is composed of a central control unit (6) for determining a value and an output means (7) for outputting the determined initial static weight value, static weight value and the like.

The input means (5) is an amplifier (5A) for amplifying the analog electric signal from the weighing means (S), a low-pass filter (5B) for smoothing the output of this amplifier, and a smoothed signal for a predetermined sampling time. It consists of an A / D converter (5C) for quantization.

The central controller (6) includes a memory (6A) for storing time-series data of sampled weighing values, a walking periodicity evaluation means (6B) for calculating the walking periodicity from the time-series data, Data section setting means (6C) for setting an initial data section (T ₁ ) and an effective data section (T ₂ ) from the time series based on the gait periodicity, and the time series data in the initial data section (T ₁ ). And a computing means (6D) for computing the initial static weight value of the walking animal or computing the static weight value of the walking animal from the time-series data in the effective data section (T ₂ ). Has been unitized as.

In this embodiment, the output means (7) displays a cow specific information and an initial static weight value or a static weight value CRT (7A).
A printer (7B) for applying a display result and three display lamps (L ₁ ) to (L ₃ ) indicating whether or not the initial static weight value is within the set value range are used.

The weigher (1) is provided with an entrance gate (G ₁ ) on the entrance side and an exit gate (G ₂ ) on the exit side. The waiting area (AR) is located in front of the entrance gate (G ₁ ), and a separator (11) for separating the waiting cow from other herds is provided in front of the waiting area (AR). There is. Further, the sorting device (10) is provided with a switching gate (G ₃ ) for switching the walking path of the cow after weighing. These entrance gate (G ₁ ), exit gate (G ₂ ), separator (11),
The switching gate (G ₃ ) is connected to the hydraulic cylinder (U ₁ ),
As (U ₂ ), (U ₃ ), and (U ₄ ) expand and contract, the structure is such that it can be opened and closed by sliding up and down or swing open and close around the vertical axis. Electromagnetic valves (V ₁ ) to (V ₄ ) for controlling the hydraulic cylinder are connected to the central control device (6) via a drive circuit (12), and the central control device (6)
It is designed to be opened and closed automatically by a command from.

Next, the procedure for determining the static weight of a cow walking on the weighing machine (1) will be described.

The signal (see FIG. 4) output from the amplifier (5A) is low-pass filtered to remove harmonic components (see FIG. 5). FIG. 6 is an enlarged view of the area indicated by b.

When the quantized weighing value data (hereinafter simply referred to as weighing value data) exceeds a set value (K ₁ ) that is slightly larger than the weight of the weighing table (1a), the cows get on the weighing table (1a). As a start, the weighing value data is sequentially stored in the memory (6A) as a sampling series. Then, the maximum value is obtained at any time from the stored sampling data by the gait periodicity evaluation means (6B). The set value (K ₂ ) which is slightly smaller than the standard static weight value of the cow is used as a threshold value, and when this threshold value is exceeded, the time point at which the first maximum value W1 appears by the data section setting means (6C) Initial data period (T ₁ ) as the starting point and the ending point when the _fourth maximum value (W ₄ ) appears
Is set. The sampling data in the initial data section (T ₁ ) set in this way are averaged by the computing means (6D) to calculate the initial static weight value of the cow.
If the initial static weight value obtained at this time falls within the set range, the storage by the memory (6A) is continued. On the other hand, when the value is out of the set range, the weighing is immediately stopped.

If the initial static weight value is within the setting range, the first maximum value W1
The weighing value data from the time when "" appears to the time when a predetermined time (T) elapses is sequentially stored in the memory (6A) as a sampling series. The maximum value: Wmax during this period is obtained by the gait periodicity evaluation means (6B), and 90% of this maximum value is used as a threshold value, and a data group having a value equal to or greater than this threshold value (total weight load of cow) Is regarded as a group of weighing value data on the weighing table (1a)), and the maximum value is examined at any time to determine the walking periodicity. In the illustration, there are eight maximum values W1 to W8. Then, the data section setting means (6C) sets the valid data period (T ₂ ) with the time point at which the first maximum value W1 appears as the starting point and the time point at which the last maximum value Wx (W8) appears as the end point. The sampling data in the valid data section (T ₂ ) set in this way are averaged by the computing means (6D) to calculate the substantial static weight value of the cow walking on the weighing platform (1a). It In the setting of the initial data section (T ₁ ) and the valid data section (T ₂ ), the number of walking cycle peaks to be included is set in advance depending on the type of walking animal and the natural frequency of the weighing means (S). can do.

When the weighing value data falls below the set value (K ₁ ), it is assumed that the cow has descended from the weighing platform (1a), and the storage of the weighing value data in the memory (6A) ends.

Next, an algorithm for controlling the opening and closing of the entrance gate (G ₁ ), the exit gate (G ₂ ), the separator (11), and the switching gate (G ₃ ) for weighing a plurality of cows will be described based on FIG. 7. . However, (Q) in FIG. 2 is a cow detection sensor such as a FO interrupter type that detects the presence of cows in the waiting area (AR), and the opening / closing control is also performed by using the information of this cow detection sensor (Q). Is performed.

Open the separator (11) (step) and guide only one of the many cows into the waiting area (AR). Close the guided separator (11) (step), waiting area (AR)
Separate the cows that have been introduced into it from other cows. Next, the entrance gate (G ₁ ) is opened (step), and the cow is placed on the weighing platform (1a). Then, the loading of the weighing data is released (step).

It is detected whether or not this weighing data exceeds a threshold value (K ₂ ) (step). If the weighing data does not exceed the threshold value (K ₂ ), the cow can determine that he is not yet fully on the weighing (1a) and can read the detection. On the other hand, if it exceeds, it is determined that the driver is completely on board, and the entrance gate (G ₁ ) is closed (step). When the entrance gate (G ₁ ) is closed, the separator (11) is opened (step), and the cow to be weighed next from a large number of cows is guided into the waiting area (AR). By the way, the separator (11) will be closed upon detection of the presence of the cow detection sensor (Q).

Then, the initial weighing is started, and the initial static weight value is first calculated (step). Then, it is determined whether or not this initial static weight value is within the set range (step). If the setting range is exceeded, the OVER indicator lamp (L ₁ ) is turned on (step). If it is below the threshold, the BELOW indicator lamp (L ₃ ) is turned on (step). If it is within the setting range, the OK indicator lamp (L ₂ ) is turned on (step).

OVER display lamp (L ₁ ) or BELOW display lamp (L ₃ )
If is turned on, the switching gate (G ₃ ) is operated to switch the walkway to (R ₁ ) (step). OK
When the display lamp (L ₂ ) of is lit (step), the switching gate (G ₃ ) is operated to switch the walkway to (R ₂ ) (step).

If the initial static weight value is within the set range, weighing is started (step). It is judged whether or not a predetermined time has passed since the start of initial weighing (step). If the predetermined time has passed, the weighing is finished (step) and the static weight value is displayed on the CRT.
Output to (7A) and printer (7B) (step). If the initial static weight value is outside the set range, the gait passage is switched to (R ₁ ) (step), and then the weighing is immediately terminated (step). After the weighing is completed, it is detected whether or not the cow has come down from the weighing platform (1a) (step), and if it has come down, the weighing data acquisition is finished (step).

When the weighing data has been taken in, close the exit gate (G ₂ ) (step) and turn on the indicator lamp (L ₁ )
Turn off (L ₃ ) (step). It detects whether there is a next cow in the waiting area (AR) (step), and if there is, opens the entrance gate (G ₁ ) (step).
On the other hand, if not, it is judged that all the cows have been weighed.

[Another embodiment]

In the embodiments described so far, in the set initial data section (T ₁ ) and effective data section (T ₂ ), the sampling data included in the section is simply averaged. In order to perform more effective smoothing on series data, a moving average calculation method can be adopted. In this case, for example, the moving average value is calculated over the effective data section (T ₂ ) using a window function such as a Hamming window as the averaging time, which is a multiple of the obtained walking cycle. In this way, the obtained moving average value is evaluated and, for example, the average or the maximum value thereof is taken as the static weight of the walking animal walking on the weighing machine (1). The block diagram of the device according to this second embodiment is
As shown in the figure, as compared with the apparatus according to the first embodiment shown in FIG. 2, the central controller (6) is further provided with a moving average value evaluation means (6E). It is different, and of course, the calculation means (6D) performs the moving average calculation as described above. It is to be noted that those parts in FIG. 6 designated by the same reference numerals as those in FIG. 2 have basically the same functions as those in FIG. 2 and will not be described further here to avoid unnecessary duplication. .

Further, in carrying out the present invention, each unit can be modified as described below.

The averaging method averages weighing value data between a plurality of maximal values that appear _{consecutively in the} effective data section (T ₂ ) to a maximal value that appears next to the maximal value, and the result is obtained. Is to average.

Furthermore, the weight calculated by the above-mentioned averaging operation is not immediately regarded as the weight of the walking animal, but is multiplied by the correction coefficient obtained in advance by experiments, or the correction value obtained in advance by experiments is added or subtracted. By doing so, it is possible to further improve the measurement accuracy.

In addition, if a damper device that controls the damping of the weighing platform (1a) is added to suppress the vibration of the sampling series, it is possible to further improve the measurement accuracy.

In carrying out the present invention, the scale (1)
If a plurality of animals are measured in parallel in the lateral direction of the walking path, each of a plurality of walking animals walking side by side will walk with a sense of security by seeing the walking of the adjacent animal. It can be expected that it has a great practical advantage.

Further, for example, when a cow whose initial static weight value is out of the set range is unloaded from the weighing machine (1), or when all weighed cows are unloaded from the weighing machine (1), the cow stops unnecessarily. In this case, it is advisable to incorporate means for forcibly dropping cows. For example, as shown in FIG. 9, a cow pusher (14) is moved from the back of the cow toward the exit side of the endless belt (13) wound on the cow walking path. . Then, the fact that the cow has stopped unnecessarily is detected from the weighing data, and the endless belt (13) is operated once. Incidentally, the position shown by (T) in the figure is the initial position of the pusher (14). In the case of this embodiment, it is preferable to provide a sharpened protrusion on the pressing surface of the pressing tool (14).

In addition, as means for forcibly dismounting cows, various means such as provision of a beating tool for cows can be considered. By the way,
When installing a hitting tool, first hit with a weak force,
If the cow still does not walk, it is recommended that the cow be beaten with increased strength, for example, repeatedly, and as the number of times increases, the strength should be increased.

Further, in the embodiments described so far, as the measurement object,
Although walking animals, in particular cows, have been mentioned, they can also be applied within the framework of the invention to the measurement of other moving bodies, for example vehicles such as trucks.

Further, in the above description, the weight measurement of one walking animal has been described, but a plurality of animals may be grouped and the weight of the group may be measured.

It should be noted that reference numerals are added to the claims for convenience of the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
